Maybe you're fishing for the sport and don't want to keep your catch. Put those fish back too.

Here's my tips for letting fish go - and helping them survive.

• Use hooks without barbs.
• Don't use a net with knots to pick the fish up. Knots can damage the fish's skin and eyes
• Bring the fish in quickly - a long fight stresses a fish and it's more likely to die.
• Cut the line rather than remove a hook from the gut or gills
• Try not to lift the fish from the water. If you do, wet your hands first so you don't damage the protective slime and scales on the fish.
• If you have to put the fish down to take the hook out, put it on a smooth, wet surface and avoid injuring the fish.
• Remove the hook carefully or if the fish has swallowed the hook, cut the line as close as possible to the fish's mouth.
• Return the fish to the water as quickly as possible.
• Before releasing the fish you might have to help revive it. Hold the fish horizontally under its body and gently move it backwards and forwards in the water. This lets the water pass through its gills. It will swim off by itself when it's ready.
